摘要(Abstract)：

为改善绝缘子气固界面电场分布，提出了表层功能梯度材料（SFGM）的概念，并采用迭代算法对220 kV GIS盆式绝缘子的表面相对介电常数分布进行优化。优化后SFGM绝缘子的表面相对介电常数分布趋势与沿面电场分布正相关，由中心导杆向外壳逐渐降低；与传统绝缘子相比，优化后的SFGM绝缘子可以显著降低绝缘子表面及周围的最大电场强度，改善绝缘子的沿面耐电性能。
In order to improve the electric field distribution at the gas-solid interface of the insulator, the concept of the surface functionally graded material (SFGM) is proposed, and the iterative method is used to optimize the surface relative permittivity distribution of the 220 kV GIS basin-type insulator. The surface relative permittivity distribution trend of the optimized SFGM insulator is positively correlated with the electric field distribution along the surface, which gradually decreases from the central conductor to the outer shell. Compared with the conventional insulator, the optimized C-SFGM insulator can significantly reduce the electric field strength on and around the insulator, thus improving the electrical resistance performance of the basin-type insulator.
